Styled Form - Copy this React, Mui Component to your project

Create a responsive newsletter signup component for a Business Consulting blog. The component should allow users to subscribe by choosing from a list of topics such as Investments, Business Planning, and Hiring Tips. Ensure the design is user friendly, professional, and visually engaging. Include input fields for the user's name and email address, as well as checkboxes for the topic selections. Add a confirmation message upon successful subscription and handle form validation for user input. The component should be fully responsive and optimized for both desktop and mobile devices.
